Some CSS/HTML Errors to fix -- 2

My small CSS/HTML Website ([login to view URL]) has some problem especially with the responsive display. Here are the following errors: - Logo is getting cut of in the right corner (Bild [login to view URL]) - The Welcome text and Button above the Top-Slider needs to get higher to the Nav-Bar. Because it get’s cut off on the left bottom side.(Bild [login to view URL]) - The lightbox doesnt work for the gallerie. The script is there but there is maybe a problem with the correct link. (Bild [login to view URL]) - On my Android Smartphone is a problem with the site (Bild [login to view URL]) - On the sub-domain “[login to view URL]”: one text section below gets cut off. (Bild [login to view URL]) PS. I only support unencrypted FTP transfer on my server. If you don't know how to set your FTP Client up for unencrypted FTP don't bit on this project.
